This high performance wireless bodypack transmitter is an ideal choice for live sound applications including theatre and concerts, as well as studio based TV production and ENG/EFP.

The DWT-B30 is part of Sony's third generation DWX series digital wireless microphone system that combines advanced digital technologies, analogue microphone expertise, wireless audio transmission technologies and an enviable reputation for stability. Sophisticated audio processing, encryption and RF transmission technologies assure secure, stable digital transmission and reception of very high quality audio with low latency.

The transmitter operates with a wide bandwidth up to 148 MHz (depending on region), and the high density 375 kHz interval channel plan enables simultaneous multi-channel operation, increasing the probability of finding unoccupied frequencies in congested metropolitan areas.

The DWT-B30 is compatible with Sony Wireless Studio control software for PC (Ver 5.22 or later) , allowing flexible remote operation. Control of up to 82 transmitters is possible using the Cross Remote function combined with the RMU-01 remote control unit (available separately).
